Symbolist painting emphasized fantasy and imagination in their depiction of objects. The artists of the movement often used metaphors and symbols to suggest a subject and favored mystical and occult themes. Influenced by Romanticism and the Pre-Raphaelite Brotherhood, the movement strived to depict the symbols of ideas. The movement originated in France and spread across Europe. Symbolists were opposed to the visual realism of the Impressionists and serious nature of the Industrial Age. Their aim was to portray mysterious and ambiguous interpretations of emotions and ideas by using unobvious symbols. Some artists, including Puvis de Chavannes, Moreau, and Redon, borrowed their imagery from Symbolist writings. These works would often contain grotesque and fantastical imagery such as severed heads, monsters, and spirits. In addition, their works sometimes contained references to the Bible and ancient myths. Other Symbolists took a more traditional approach, using lines and colors to produce emotional effects. The Symbolist movement was important to the development of the Surrealism.
